To tackle the problem of wind erosion it is necessary to know where it occurs and how intense it is. To deal with the problem effectively, the Australian and State governments, along with Natural Resource Management (NRM) regional bodies, need to know:
- where the wind erosion is occurring;
- how severe it is; and
- if the NRM projects aimed at reducing erosion are making a difference.
Monitoring wind erosion
Measuring wind erosion as it changes in space and time is very difficult; wind erosion varies across the landscape and occurs at different times of the year. There are several ways to measure and monitor wind erosion; at DustWatch we provide information on wind erosion patterns across a range of temporal, spatial and measurement scales.
Key patterns to look for when monitoring wind erosion:
- when does dust usually occur in my region? Look for yearly, seasonal or monthly patterns.
- how do the patterns relate to the climate? Do periods of high erosion correspond to drought periods, and are there some periods of erosion which can't be explained by climate?
- how do the erosion patterns relate to other external information, such as ground cover levels, land use, and fire patterns?
How do I monitor wind erosion in my region?
At DustWatch, we have three nationally-funded projects providing information on wind erosion patterns: Wind Erosion Histories, Modelled Wind Erosion and Community DustWatch. Read about these projects and browse open-source data and information. The data can be used by NRM bodies and the Australian Government for resource condition reporting. The same products would also assist in identifying areas for Caring for our Country (C4oC) investments.
